20100190664 | INVERT EMULSION BASED COMPLETION AND DISPLACEMENT FLUID AND METHOD OF USE - A method of cleaning a wellbore prior to the production of oil or gas, wherein the wellbore has been drilled with an invert emulsion drilling mud that forms an invert emulsion filter cake is disclosed. The method may include circulating a breaker fluid into the wellbore, where the breaker fluid includes a non-oleaginous internal phase and an oleaginous external phase, where the non-oleaginous phase includes a water soluble polar organic solvent, a hydrolysable ester of a carboxylic acid, and a weighting agent, and the oleaginous external phase includes an oleaginous fluid and an emulsifier, and where the hydrolysable ester is selected so that upon hydrolysis an organic acid is released and the invert emulsion of the filter cake breaks. | 07-29-2010 |
20110306524 | DRILLING FLUID AND METHODS - A drilling fluid comprising: a non-ionic surfactant including: a branched alcohol ethoxylate and/or a capped alcohol ethoxylate; and a detergent builder. | 12-15-2011 |
20120295821 | High Performance Drilling Fluids with Submicron-Size Particles as the Weighting Agent - Drilling fluids comprising a carrier fluid; a weighting agent that comprises sub-micron precipitated barite; a particle having a specific gravity of greater than about 2.6; and, a bridging agent that is not the submicron-precipitated barite or the particle. The weighting agent has a particle size distribution such that at least 10% of particles in the sub-micron precipitated barite have a diameter below about 0.2 microns, at least 50% of the particles in the sub-micron precipitated barite have a diameter below about 0.3 microns and at least 90% of the particles in the sub-micron precipitated barite have a diameter below about 0.5 microns. The particle has a specific gravity of greater than about 2.6 is not sub-micron precipitated barite. The ratio of the sub-micron precipitated barite to the particle is about 10:90 to about 99:1. The bridging agent comprises a degradable material. | 11-22-2012 |

The method comprises (a) providing a drilling fluid; and (b) treating the drilling fluid by adding a composition thereto which comprises (a) an alkylene glycol, (b) a polyol having first and second primary hydroxyl groups, (c) an unsaturated vegetable oil, and (d) an alkoxylated alcohol. | 10-10-2013 |
20140213489 | DRILLING FLUID AND METHODS - A drilling fluid comprising: a non-ionic surfactant including: a branched alcohol ethoxylate and/or a capped alcohol ethoxylate; and a detergent builder. | 07-31-2014 |
20140336086 | VISCOSIFIERS FOR DRILLING FLUIDS - A drilling fluid comprising 0.1 to 50% by weight of at least one viscosifier selected from epoxidized fatty acid esters, wherein the fatty acid of the fatty acid ester is derived from natural oils or animal fats, and the fatty acid is substantially fully esterified with monohydric or polyhydric alcohols or mixtures thereof. | 11-13-2014 |
20150353806 | BIODEGRADABLE ADDITIVE CONCENTRATE IMPROVING THE LUBRICITY OF AQUEOUS SLUDGES, USE THEREOF AND AQUEOUS SLUDGE FOR DRILLING - Biodegradable additive concentrate with pour point according to standard ASTM D 97 below −5° C., improving the lubricity of water-based muds, comprising at least one compound selected from the group consisting of: | 12-10-2015 |
20160024368 | DRILLING FLUID AND METHODS - A drilling fluid comprising: a non-ionic surfactant including: a branched alcohol ethoxylate and/or a capped alcohol ethoxylate; and a detergent builder. | 01-28-2016 |
20160060500 | Composition and Methods for Completing Subterranean Wells - Well treatment compositions comprise at least one surfactant, and an ionic liquid, a deep eutectic solvent or both. When added to spacer fluids, chemical washes or both, the compositions promote the removal of non-aqueous drilling fluids from casing surfaces. Additionally, the treated casing surfaces are water wet, thereby promoting optimal bonding to cement. | 03-03-2016 |
20160102237 | WELLBORE SERVICING COMPOSITIONS AND METHODS OF MAKING AND USING SAME - A method of servicing a wellbore in a subterranean formation comprising preparing a wellbore servicing fluid comprising an alkoxylated humus material and an aqueous base fluid, wherein the alkoxylated humus material comprises an ethoxylated humus material and/or a C3+ alkoxylated humus material, and placing the wellbore servicing fluid in the wellbore and/or subterranean formation to modify the permeability of at least a portion of the wellbore and/or subterranean formation. A method of drilling a wellbore in a subterranean formation comprising preparing a drilling fluid comprising an alkoxylated humus material and an aqueous base fluid, wherein the alkoxylated humus material comprises an ethoxylated humus material and/or a C3+ alkoxylated humus material, and placing the drilling fluid in the wellbore and/or subterranean formation. | 04-14-2016 |
